By having Beatrice on the field, you have access of milling a lot more troll cards.
Examples of such is milling Blaze Accelerator Reload for Volcanic Scattershot's use and just laugh hysterically like Magat (Trust me, look at his face)

Warning: This is Dam Son's Journey for Troll......Troll. So do not go around trying this in the competitive scene unless you want your hopes and dreams crushed by a Solemn Strike waiting for you.
